Positive vaginal bacillus means the presence of vaginal bacillus, which is a beneficial bacteria in the vagina that can maintain the acid-base balance in the vagina and resist the invasion of foreign pathogens. Vaginal secretion tests show a high amount of positive vaginal bacilli, indicating that the vaginal environment is good, the acid-base balance is normal, and there is no inflammation and infection. The vagina is mainly dominated by vaginal bacilli and vaginal epithelial cells, which maintain the normal balance of the vagina to avoid vaginitis. If the vaginal bacillus is negative, it means that there is inflammation and infection in the vagina or there is low resistance, so it is necessary to use anti-inflammatory drugs or lactobacillus capsules for vaginal plugging to control vaginal inflammation, maintain the pH balance of the vagina, and improve the resistance of the vagina. If the vaginal bacillus is negative, accompanied by vulvar itching and other adverse reactions, it is recommended to go to the hospital in time for treatment.
